Why purchase a Sigma 18-250mm OS superzoom lens?First and foremost, photographers who use entry level digital SLR cameras are affirming the benefits of the Sigma 18-250 lens. However, not to be misleading, this lens does not top every report by camera techies. Their job is to be ultra critical and there are several attributes to think about before making your final decision to buy.None the less, that being said, nearly each and every Sigma 18-250mm OS review has wonderful things to express about this superzoom device.Yours truly is the proud owner of what I would consider one of the two best pieces of glass I own.While visiting a local art festival this past weekend, I was commenting on one of the vendor’s photography offerings and asking what equipment he used to take his photos.The discussion got around to the question of how he might convince his wife that he needed a new Sigma 18-250 super zoom lens. It seems he carries his camera with him most of the time but does not favor taking his entire camera bag every time he leaves the house.This is where I came up with my “short list” of 3 really good reasons that might just be compelling enough to convince a compassionate spouse of your need:Less Weight, thus, Easier on your Shoulder (or back). Consider this – if you attach a super zoom lens to the front of your entry level digital SLR, you don’t need to transport that klunky camera bag all over with you. No camera bag means no aches and pain in your shoulders and back. If you have existing physical issues, this could be an excellent reason for acquiring a new lens.

When the opportunity is readily available, you are too. Can’t tell you how many times my wife has wanted me to get a particular shot, and I have had the wrong lens on my camera. Her response is usually something like, “What good is the camera when you can’t take the pictures you want. By the time you fiddle around with changing stuff, it’s too late!”
Well, with a super zoom lens, no more mad rush to switch to the correct focal length while your shot walks away, flies away, or fades away. You can get the great landscape shot or the long range photo of a wild critter without having to change the lens.

$$$ – This could be the best, depending on your spouse. If finances are a major consideration, this is a great argument. The glass you place in front of your camera’s image sensor is not inexpensive. And it just makes good sense to get as much value for your money as possible. The Sigma 18-250mm OS lens qualifies as more than just one lens. It really covers the range of 2 or 3 lenses with outstanding top quality glass. Yes, you might acquire less costly, but any time quality is taken into consideration, the cheaper lenses are not always the most cost-effective in terms of hanging on to them for an extended period of time. Frequently, if you spend very little for your camera lens, you wind up not being content with the acquisition and replacing it very quickly. So, pay a few pesos more and get something that will last for a very long time.Pretty powerful stuff, right? My new friend at the festival had not thought about this approach.So you can have a solitary walk around, or “all in one” lens for your Digital SLR camera that will do the job of more than one lens, at least as well as the manufacturers’ own merchandise, save the stress on your body, get quick shots without changing gear, and conserve money in the deal.How can you go wrong?
